Define "great cam" because that means many different things to many different people. Do you want something you can cruise in or something mainly for the track and how high are you planning on spinning the motor?

If you want crazy lol I'm going with the Streetsweeper high TQ cam for my GTO. The MS4 maybe too big for driving around but on the other hand I've seen some people on here running that beast in their DD.

I'm running the original 241 heads, ported, polished and milled, and the Trickflow 238/242 .595/.595 112lsa with all supporting mods, and built a4. I love it and with under .600" lift the valve springs will last longer... Cam rated at 3,000-7,000 rpms and pulls like a freight train... When I get traction
